On parametric effects of wettability, surface roughness and porosity on nucleate pool boiling heat transfer

Abdul Fattah Abood, Sahar LU (2015) 7 th Baltic Heat Transfer Conference p.1-6
Abstract (Swedish)
Phase-change heat transfer enhancement is of critical importance to meet high cooling demands. Recently, surface engineering (surface modification) is emerged as a promising heat transfer enhancement method, especially with the development of nanotechnology. Surface parameters such as wettability, surface roughness and porosity are modified by surface engineering. This work aims to discuss the parametric effects of wettability, surface roughness and porosity on pool boiling heat transfer performance by selecting several promising micro/nanoscale enhancement techniques as examples. More theoretical and experimental efforts are needed as phase-change phenomenon on micro/nanostructures is very complicated due to the multiscale of the... (More)
